The Lowdown

Alright crew, Rusty checkin’ in. We’re lookin’ at Kennebunk Beach, and I gotta be honest – it’s a rough stretch. This whole 16-day window is pretty much a write-off for any decent surf.

The water temp’s a touch warmer than usual for this time of year, sittin’ around 68°F back on the 16th, but that’s the only good news. The pattern from here on out is flat, weak, and mostly messy.

The only break on the map is Kennebunk Beach. This is an intermediate spot that’s fairly consistent when there’s swell, but it’s sheltered, so it needs the right angle from the ENE. That angle just ain’t showin’ up with any power.

The first record is Sunday afternoon, August 16th: a measly 1ft of SE swell with a 9-second period, and a SSE cross-breeze messin’ it up. The combined swell energy is only 12 – that’s a ripple. No good.

Monday the 17th gives us a bit more size – about 4ft – but it’s a short-period 5-second S swell with a cross-onshore wind. Choppy, ugly. Tuesday the 18th morning is the cleanest of the first week: a light NE offshore wind with a 4ft SE swell (period 7 secs, energy 111). It’s small and short-period, but at least clean. Still, we’re callin’ “poor surf conditions” so don’t get excited.

From Wednesday the 19th through Wednesday the 26th, it’s a long flat spell. Swell barely touches 2ft, and the combined energy is mostly under 100. Winds are cross or onshore. There’s a clean morning on the 20th with a 2ft swell, and another clean one on the 24th with 1ft, but you’re paddlin’ for knee-high dribble.

Then on Thursday the 27th of August, we get a pulse. Swell hits about 5ft from the NE, but the period is a short 6 seconds. The combined energy jumps to 275 – that’s moderate. Winds are light from the ESE, keepin’ it cross-off and clean. The comment says “surfable waves but very ordinary conditions,” and the score is a 1 out of 10. It’s the best of a bad bunch, but it’s short-period and not the right direction for the break. That afternoon drops to 3ft.

From Friday the 28th through Sunday the 31st, we’re back to tiny, weak swell under 2ft with onshore or glassy winds. There are glassy mornings on the 29th and 30th, but the swell is only 2ft from the SE with a period of 8-9 seconds and energy below 120. Flatter than a pancake.

So, the standout? There isn’t one. If you’re really itchin’, Tuesday the 18th morning and Thursday the 27th morning are your best shots – and they’re both poor. This is a typical dry spell for the area. Forecasts can shift, but right now, leave the board at home.

Information about the Kennebunk Beach Surf forecast

The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Kennebunk Beach is 17 km (11 miles) from Biddeford. If you plan a vacation in Maine, look for hotels and other accommodation in Biddeford. Biddeford has rooms for a wide range of budgets as well as car hire and transport links.
